Social media users are divided over what they can see in a new photograph that's emerged online.
The optical illusion is an image of a dog, which began circulating the internet last week.
But some users haven't been able to see the dog - instead, they found a clown.
"This frazzled my brain," one person wrote on Twitter, with another adding the image was "creeping me out".
The key to being able to see the dog is its eyes, which are at the top of its body. The clown, which is facing to the left, can be found as its right eye is the dog's nose.
The image has been shared hundreds of times across social media but it's unclear where it came from.
It's the latest illusion to divide the internet. In 2015, social media users couldn't decide if the world's most divisive dress was white and gold or blue and black.
Another optical illusion left commenters confused over whether these sneakers are black or white.
In 2018, an audio clip left people divided over if they heard 'yanny' or 'laurel'.
While there was probably an explanation to do with frequencies, most Reddit users chalked it up to "black magic".
